Abstract
A human immunodeficiency virus type (HIV-1)-based lentiviral vector pseudotyped with the vesicular stomatitis virus envelope glycoprotein and encoding the GFP reporter gene was used to evaluate different methods of lentiviral vector titration. GFP expression, viral DNA quantification and the efficiency of vector DNA integration were assayed after infection of conventional HIV-1-permissive cell lines and human primary adult fibroblasts with the vector. We found that vector titers based on GFP expression determined by flow cytometry may vary by more than 50-fold depending on the cell type and the promoter-cell combination used. Interestingly, we observed that the viral integration process in primary HDFa cells was significantly more efficient compared to that in SupT1 or 293T cells. We propose that determination of the amount of integrated viral DNA by quantitative PCR be used in combination with the reporter gene expression assay.
